Barium tungsten electrode is widely used in high-intensity gas discharge lamps, electron tubes and other fields due to its excellent electron emission performance and high stability. Its anti-ablation performance, that is, the ability to resist material loss under extreme conditions such as high temperature and high current, is a key indicator for evaluating its service life and stability.

Barium tungsten electrode is an electron emission material composed of tungsten (W) and barium (Ba) compounds. Its thermal electron emission characteristics have important applications in vacuum electronic devices, light sources, medical and industrial fields.

Barium tungsten electrode is a high-performance thermal electron emission cathode widely used in vacuum electronic devices (such as high-power microwave tubes, X-ray tubes, etc.). Its electron emission mechanism involves complex physical and chemical processes, and the core lies in the single atomic layer coverage of barium (Ba) atoms on the surface of porous tungsten substrate.

Barium tungsten electrode plays a vital role in high-resolution microscopy, mainly used as an electron source, providing a high-quality electron beam to achieve high-resolution imaging.
